Since about 13 weeks for me which is cool cuz it took forever with my third and lol I wasn't for sure but when I was my last appt I said so I think the baby is moving now is that right and he said yep you can hear it on the doppler. It's not.constant and its when I'm laying down :)

I'm 15 weeks and keep feeling only what I can describe as the feeling as if you were holding a goldfish in your fist and it was wriggling around. Coolest thing ever :) it only happens a few times a day....but it's awesome when it does :)
